About our mission
At A3 Academy, we offer a transformative experience for serious baseball players, combining top-tier training with an unmatched, flexible academic environment. Our athletes train and push each other year-round at an elite level, facing stronger competition than traditional schools can offer. With a schedule that includes the ABA conference, Florida Junior Colleges, and other premier academies, our players are constantly challenged without limitations. Paired with a state-of-the-art classroom, computer lab, and tutoring, A3 Academy ensures that athletes bring their virtual curriculum to life and excel both academically and athletically, preparing them to thrive at the next level.
A3 Academy
A3 Academy is not a travel team. A3 Academy replaces high school and middle school and utilizes virtual and in-person learning curriculums to push student-athletes to their limits.
A3 Academy student-athletes are monitored daily in our computer lab and study hall to stay locked in academically.
95% Commitment Rate
With very few exceptions, every senior or post grad that has ever completed the school year with A3 has college baseball offers. While some seniors opt to take an additional post-grad year with A3, the A3 coaching staff is unmatched in providing opportunities for college placement.
Home of the Spartans
A3 Academy (Jacksonville, FL) players are challenged daily with a well-rounded coaching staff with emphasis on each position. A3 staff includes full-time strength and conditioning coaches, full time pitching coaches, hitting coaches, infield, outfield and catching coordinators. Most of the A3 coaches played professional baseball - with our lowest coaching experience being former Division 1 players. The organization is structured and ran like a hybrid between a professional organization and collegiate program - ensuring players get the best training possible while becoming a family!
A3 Timeline

ELITE COMPETITION

A3 challenges players during training and during games. A3 faces far superior competition of a traditional high school player, playing in the prestigious ABA (Academy Baseball Association) and vs Florida Junior Colleges - forcing our players to compete against college, junior college and stacked academy level teams. A3 players go through a highly regimented Fall training schedule made to build speed, power and size. A3’s spring season is a 40-50 game schedule built to create comfort in game environments.
Spartan Life
All A3 players are enrolled in Virtual School or do in-person learning - giving them schedule flexibility to participate in all baseball activities. Finally, A3 monitors student-athletes with pace and grade checks - reinforcing students to stay on task and keep their eligibility for practices and games.

A3 Timeline
Fall

The Fall is designed for gains to velocity, speed, bat speed, strength, arm strength, size, athleticism and muscle composition. Each program is designed to make the player more "toolsy" and more of an impact player.

Winter

The Winter is a time for feedback, shut down, and recruiting help for those uncommitted players. We begin developing a player development road map for what the player needs improvement at and what their standing is within our organization heading into the spring. We conduct exit meetings with each player that are an honest assessment of each part of their game.

Spring

The Spring is game-intensive. A3 schedules maintenance lifts so the players don't lose what they've gained in the Fall. But the spring is more about in-game development vs other academies, Junior Colleges and other small colleges. As the players play a more difficult schedule, they are forced to adapt to the level of competition.

Summer
A3 Academy fully supports travel baseball and allows all players to continue playing with their existing summer teams. The players are "off" from the academy for the summer.
All Bases Covered
Elite Schedule
Toughest schedule in the country. Play against top Florida Juco's, colleges and academies.
Player Development
Most A3 players see a significant jump in size, strength, velocity, arm strength, speed and power. Our training regimen exceeds anything a traditional student can do.
College and MLB Exposure
It is not uncommon for A3's games to be covered by MLB scouts. In addition, A3 staff works every year for a 95% commitment rate since it's inception in 2019. We help each player personally get committed to school.
Scholarships Available
Every year we provide scholarships to deserving players meeting certain requirements. We seek players who come from low income / single parent homes, yet have maintained academic excellence and have elite baseball talent. Ask about our scholarship program to see if you qualify.
Co-op & Tutors
A3 partners with the best home school co-op in Tampa Bay. Allowing us to provide optional, in-person learning options for Math, English and Science through our Core Athlete program. Players have the option to add tutoring at the same location. All players have the option of selecting their curriculum - virtual, homeschool, etc.
Boarding
A3 partners with a beautiful apartment complex that is close to our fields that allow us to house players from outside of the greater Tampa Bay area. One of our head coaches lives in the same complex and helps with supervision. For more information, please inquire.
